New USB-powered devkits for K-30 and K-33 sensors enable rapid prototyping projects

Researchers, scientists, engineers and students will all appreciate the new development kits for the K-30 and K-33 sensors. These kits include the sensor, a USB cable for power and data communication, and a free software development library.

The K-30 sensor measures 0-10,000ppm, while the K-33 sensor measures up to 30% CO2 by volume. In addition, the K-33 sensor includes a tube adapter cap so that the CO2 can be drawn from a remote location.

The software, written in Visual Basic .NET framework, can be used as a stand-alone application. Since it abstracts the hardware layer, it can also be called from your own custom application.

Can carbon dioxide in the ground poison you? We ask an expert to find out.

Recently I received a call from a customer who claimed that every time it rained, the pilot light on his furnace went out, and he got so sick he was unable to leave the house. An HVAC specialist determined it was CO2 in the basement. Since I’d never heard of this, I asked Keith Volsted, President of VSI Environmental in Ingleside, Illinois for some facts on the subject.

Keith, is carbon dioxide hidden in the ground around our homes? CO2 in soil typically comes from natural decomposition. I have encountered several homes with elevated CO2, all built on farm land. Manure, fertilizers, nutrients are all added to the soil to enhance crop output. These products can combine and break down over time to create naturally occurring CO2 or soil gas which can be sucked or drawn into a home.

Is the CO2 literally pushed through the basement walls? Rarely will you find soil gas pushed into a home. Read the rest of the article here...
